Rig Veda 8.90

ā no viśvāsu havya indraḥ samatsu bhūṣatu upa brahmāṇi savanāni vṛtrahā paramajyā ṛcīṣamaḥ

May Indra, who in every fight must be invoked, be near to us. May the most mighty Vritra-slayer, meet for praise, come to libations and to hymns.

tvaṃ dātā prathamo rādhasām asy asi satya īśānakṛt tuvidyumnasya yujyā vṛṇīmahe putrasya śavaso mahaḥ

Thou art the best of all in sending bounteous gifts, true art thou, lordly in thine act. We claim alliance with the very Glorious One, yea, with the Mighty Son of Strength.

brahmā ta indra girvaṇaḥ kriyante anatidbhutā imā juṣasva haryaśva yojanendra yā te amanmahi

Prayers unsurpassed are offered up to thee the Lover of the Song. Indra, Lord of Bay Steeds, accept these fitting hymns, hymns which we have thought out for thee.

tvaṃ hi satyo maghavann anānato vṛtrā bhūri nyṛñjase sa tvaṃ śaviṣṭha vajrahasta dāśuṣe 'rvāñcaṃ rayim ā kṛdhi

For thou, O Maghavan, art truthful, ne'er subdued and bringest many a Vritra low. As such, O Mightiest Lord, Wielder of Thunder, send wealth hither to the worshipper.

tvam indra yaśā asy ṛjīṣī śavasas pate tvaṃ vṛtrāṇi haṃsy apratīny eka id anuttā carṣaṇīdhṛtā

O Indra, thou art far-renowned, impetuous, O Lord of Strength. Alone thou slayest with the guardian of mankind resistless never-conquered foes.

tam u tvā nūnam asura pracetasaṃ rādho bhāgam ivemahe mahīva kṛttiḥ śaraṇā ta indra pra te sumnā no aśnavan

As such we seek thee now, O Asura, thee most wise, craving thy bounty as our share. Thy sheltering defense is like a mighty cloak. So may thy glories reach to us.
